Developing component based adaptive applications in mobile environments

ABSTRACT

Today, although the system supports for developing distributed applications become mature, they are inadequate for mobile environments where the runtime resources vary considerably or even disappear spontaneously. The objective of our work is to provide appropriate supports to facilitate the development of applications that adapt their behaviors to mobile environment changes. In this paper we present a framework based on a structured adaptive component model and two underlying middleware services, respectively, for monitoring environment variations and for coordinating adaptation actions of several components. We demonstrate the validity of our ideas through an adaptive video on demand application based on a prototype implementation of our framework. We also give the benefit and overhead of the proposed adaptation mechanisms.
